| Summary:

Selected as the next NASA Medium Class Explorer mission, SPHEREx, the
Spectro-Photometer for the History of the Universe, Epoch of Reionization, and
Ices Explorer is planned for launch in early 2025. SPHEREx calibration data
products include detector spectral response, non-linearity, persistence, and
telescope focus error measurements. To produce these calibration products, we
have developed a dedicated data acquisition and instrument control system,
SPHERExLabTools (SLT). SLT implements driver-level software for control of all
testbed instrumentation, graphical interfaces for control of instruments and
automated measurements, real-time data visualization, processing, and data
archival tools for a variety of output file formats. This work outlines the
architecture of the SLT software as a framework for general purpose laboratory
data acquisition and instrument control. Initial SPHEREx calibration products
acquired while using SLT are also presented.
